摘要

胍基乙酸(GAA)是肌酸的天然前体，参与生理能量的生成。试验选用699头6 ~ 30 kg断奶仔猪，饲喂不添加(CTRL)、添加0.12% GAA的基础饲粮(饲粮1 ~ 4期，共4期)。饲粮1、2期，与GAA猪相比，CTRL组平均日增重显著提高(P < 0.05)，料重和饲料系数显著降低(P < 0.05)。在饲粮3期，CTRL组猪的体重倾向于(P < 0.10)高于GAA组猪，而在饲粮4期，GAA组猪的生长倾向于(P < 0.10)高于CTRL组猪。在整个试验期内，与GAA组相比，CTRL组的饲料效率显著提高(P < 0.05)，生长速度显著加快(P < 0.10)。综上所述，GAA在断奶后期对平均日增重的提高潜力较小。

Guanidinoacetic acid as a feed supplement offered to weaned piglets

ABSTRACT Guanidinoacetic acid (GAA) is a natural precursor for creatine, which is involved in physiological energy generation. Six hundred and ninety-nine weaned pigs (6-30 kg) were fed a basal diet (Diet 1-4, corresponding to four phases) without (CTRL) and with 0.12% GAA supplementation. Pigs in the CTRL group displayed higher (P < 0.05) average daily gain and lower feed conversion ratio, and body weight, during the periods of Diet 1 and 2, compared with GAA pigs. In the period of Diet 3 CTRL pigs tended (P < 0.10) to be heavier than GAA pigs, whereas in the period of Diet 4 GAA pigs tended (P < 0.10) to grow faster than CTRL pigs. Over the entire experimental period CTRL compared with GAA pigs displayed improved feed efficiency (P < 0.05) and tended (P < 0.10) to grow faster. In conclusion, GAA did show minor potential to increase average daily gain in the last part of the weaning phase.
